Recently I was trying to figure out what sort of tie was originally worn with this dress by the designer Pat Premo, and lo and behold, I found the dress, in an ad dated 1954 (Damn Good Vintage Blog is the source of the ad).
The beautiful dress, minus its original tie, is now available in my webstore. I'm not sure if that white over-collar was ever part of my dress. Mine also would not have had a belt, with a waistband constructed to be like a belt. So it’s similar, but not exactly the same dress.
I don't have the ad model’s 20" waist, but you can see the dress does quite a bit to flatter one’s waist anyway!
